INTRODUCTION
Lutzomyia evansi is a recognized vector of Leishmania infantum in Colombia and Venezuela.
OBJECTIVE
To describe and illustrate the morphological abnormalities in Lu. evansi females captured in a rural focus of visceral leishmaniasis in Trujillo, Venezuela.
MATERIALS AND METHODS
Phlebotomine sand flies were collected using CDC light traps, Shannon traps and aspiration in resting places. The identification was performed according to Young & Duncan (1994) and drawings were made using a microscope with camara lucida .
RESULTS
Abnormalities in the cibarium of Lu. evansi were detected in 4 (0.12%) females of the 3,477 adults that were studied.
CONCLUSION
Lutzomyia evansi can have uncommon morphological variants associated with an increase in the number of teeth in the cibarium and their arrangement, which may lead to errors in the taxonomic identification of anomalous specimens. The study of such deformities can serve to avoid taxonomic identification errors.
引言
伊氏卢蛉是哥伦比亚和委内瑞拉公认的婴儿利什曼原虫的传播媒介。
目的
描述并说明在委内瑞拉特鲁希略内脏利什曼病农村疫点捕获的伊氏卢蛉雌虫的形态异常。
材料与方法
使用疾控中心诱蚊灯、香农诱捕器并在休息处进行抽吸来收集白蛉。根据扬和邓肯（1994年）的方法进行鉴定，并使用带有明场显微镜绘图。
结果
在研究的3477只成年白蛉中，有4只（0.12%）伊氏卢蛉雌虫的下咽发现异常。
结论
伊氏卢蛉可能有不常见的形态变异，与下咽牙齿数量及其排列的增加有关，这可能导致对异常标本的分类鉴定出现错误。对这类畸形的研究有助于避免分类鉴定错误。
